Missing photos

[Bob Reite]

Well now! New attachments/photos created After the move are working! So the old photos are in the wrong directory! Should be easy to find where the new photos/files are being placed and then copy the old ones to the same place. Note that I say copy not move, just in case it doesn't work. Once you are sure they all work, then you can go ahead and delete the now duplicated files from the original location.

I think I have found a big clue to the broken links problem. (near the end here)

Bob,

Not sure if your directory theory matches all the symptoms; it might.

Historical note for reference: the site came up in its new home on Aug 29.

• Posts made with images, after the move, seem to be working as expected, even showing inline.
• But not always showing inline. In this is a post I made just after the move.

  The small image '16-pin-chip.png' in that message originally displayed inline. Now it just shows as a link. The link does work.
• The big problem is that many posts from before the move contain image links that are broken.

Clicking on a broken link gets this result

Information
The selected attachment does not exist anymore.

Here's a thread I shared earlier.
It provides examples for the following points.

• Whether the image was placed inline or as a simple attachment does not matter on broken links. Tyler's messages in the Vacuum thread with images are all just attachments (not inline) and have broken links. Other cases of broken links I have seen were placed inline in the message.
• It is not just images that have broken links. I have seen pdf files with broken links.
• Big Clue: For broken links the user ID of the poster is key. I just realized today how consistant and important this is.
  
  In the Vacuum pump thread above, Tyler posted several messages with attached images. All of those links are broken. Several other people posted messages in that same thread that had attachments. None of those links were broken.
  
  Richard has said his images are broken. I started looking through Richard's pre-move posts. The first I looked at had a working image that even showed inline, but then I remembered he had replaced some missing images. I went back further in time and never found an image in his posts that wasn't broken.
  
  Here's an example from 2004.

Who else? I seemed to remember a broken link from Jon Rosenstiel. I looked back through his posts. All with attachments seem to have broken links. Here's one from 2012:

So for some users, all attachments to messages, posted before the site move, seem to have broken links to those attachments.

Here are four users I have found so far who have this problem with their old posts. There are probably others.
Richard Hull
Jon Rosenstiel
Joe Gayo
Tyler Meagher

Conclusion
The broken link problems seem to affect all attachments in older posts made by only some users. But those users seem to have all their attachments (pre-move) with broken links.

It must have something to do with either...

• An aspect of database indexing to uploaded files that relates to UserID.
  or
• Accessing places (directories) where uploaded files were stored, if they are grouped by UserID

I found four so far. What other users have the broken link problem?

Interesting! My old password was changed about 4 or 5 year ago. I forget the issue, but nonetheless the perfesser loaded up the new password for me and thus, my sign in password ID is not what it was when the earliest posts were done, mainly many of the FAQs. Any one else in the above list had a password change? I can't seem to re-install images in the old FAQs and have them take. As you know I have full edit privileges. I have found textual issues in re-reading my old FAQs. Spelling issues, etc. I correct those and it takes on the resubmit. I think the images may be related to what Bob mentioned on attachments.
I have always only used attachments, since day one.

I do remember changing my password a few years back, but I don't recall why.

I just ran across something that may (or may not) be related to all of this.
A recent forum search for "hornyak button" turned up the following thread.
viewtopic.php?f=13&t=5131&p=35070&hilit ... ton#p35070
Top post in the thread is either from Richard Hull or Richard Hester, but when I view it it's marked "by guest » Wed Jan 16, 2002 11:08 am. Also, the "by guest" moniker has been applied to everyone else in the thread but me.

And another odd thing, when I look back through the posts in the Radiation Detection forum (page 55) I see no posts from Jan 16, 2002. Same result when searching my posts. ("your posts" in the quick links menu) No posts from Richard or myself (or anyone else) on Jan 16, 2002.

Richard,
As one of the broken link people your info is important.
You shared something about (privileged) entering text changes but not being able to "some thing" I don't understand.

When learning about the missing images in the FAQs I thought you reported fixing some of the missing images until you realized it was an endless task.

So here is a link to a key FAQ. Was the image at the end initially missing? did you in some way replace the missing image?

I think I remember you saying you tried to fix missing images for your posts until you realized it was an endless task.

Good eye, Rex!

This one I did fix, however, the next two I did not fix as when I deleted and replaced the images they did not appear and it said, not uploaded yet. I then gave up. I had to go back to my old XP computer to fish out those ancient images. Took about 1/2 hour and failed, I just gave up trying to fix things. The newbies are the current losers wading into the FAQs. So sad.

As an admin person here I have across the board editing and erasure rights on any posting. I mentioned pix repairs way or may not work for me...Mostly NOT. However I can go into any ancient posting of mine with or without images and correct the text...misspells, grammar, punctuation and submit....Text changes made by me always take on re-submitting and do benefit from corrections and deletions in all ancient postings.

Edit: Hey! I just tried and successfully up loaded replacement photos in three HV FAQs! good news so far. I will try as time permits to upload the old images if I can find them spread over 3 interim computers around here. XP, win 7 and win10. Being me, I stayed with XP until 2014. I still like it a lot and have and use the old computers in the labs. Win 7 was also good. Win 10 I just suffer with.

Making some progress on the pictures. All pictures except the broken links should now be working. The broken links are problematic and I think some field is corrupted and may need to be merged from an older backup (he sighs).

In the early days, for a very short time, it was permissible for visitors to post to the forum without logging in. GUEST might mean a visitor who had not registered or a member that did not sign in. It was obvious quickly that there was no way to identify who the Guest was as posts were not usually signed. Opening the forum for non registered visitors to post just does not work.
