No thumbnail

attroll · October 3rd, 2007, 12:43 AM

I did a new install on one of my sites that did not have a gallery before I moved it to my current licensed site and I found a problem.

When I uploaded a photo and then moved it the image to another category. The thumbnail in my Recent Photos on the PP front page does not display. It says No Thumbnail.

I went to the admin functions did these and it does not fix it.
Check for and create missing thumbnails.
Rebuild all thumbnails
Rebuild all medium images
Check here to recalculate photos/posts numbers and check children
Check here to scan for duplicate entries for same photo
Check here to update your user table last photo field

Any help would be appreciated before I move this to my licensed site.

The problem went away. I just logged in to the site again and it is now working. Weird.

Same thing happened to me just now. Moved an image from a category to my user album, and the thumbnail disappeared. Rebuild thumbnails didn't help.

The thumpnail is missing in the PP frontpage ("no thumbnail" image is displayed), but it's visible when I look at my album page.

I tried loging out and back in, as you wrote above, but that didn't help.

IN admin global options turn off the category cache and see if this helps.

I switched off the category cache, but it didn't help. On the frontpage, I can see the thumbnail in the "Random Images" area, but in "Recent Photos" or "Most Popular Images" I still get the "no thumbnail" message.

Some more info: the thumbnails show up 15-20 minutes after I've moved a picture. Looks like some sort of cache problem to me, so I changed Global Options->"Minutes to cache index page data for featured photos" to 0, which solves the problem. I don't know if there will be any performance implications though.

Could this be fixed by some option to invalidate the cache when i picture is moved or edited?

We do issue a cache update if the photo is moved like so

Code:

Content visible to verified customers only.

I dont understand why your cache would not update there.

I took a look at the database, and the timestamp in the pp_cache table changes to another non-zero value immediately after I move a picture. No thumbnails, though. If I manually reset the timestamp to 0, the thumbnails become visible.

Does this give you any clues?

Where does that source code come from, BTW? I tried to grep for it and found occurences of "move_image_cat" in 4 files, but none of them had the code in your quote.

editphoto is where my code came from

and the other file is adm-photo and both reset the cache.

The cache if it is 0 things should update anyway glad turning it off helps

It looks different in my source (I've got 6.02). From line 513 in editphoto, the code is

Code:

Content visible to verified customers only.

without any update of the cache db table.

You can try making that block this

Code:

Content visible to verified customers only.

xrvjorn · April 18th, 2008, 07:04 AM

I tested that and it didn't help. Just to make sure I rebooted the server, but still no joy. Are there more people out there having the same problem or is it only me and attroll?

Chuck S · April 18th, 2008, 08:01 AM

Its not a widely seen thing no as most people the cache refreshes fine.

Quarterbore · June 23rd, 2008, 08:47 PM

I just had the same issue. Turning the cache off did not fix the problem but when I setthe cache time to '0' the thumbs appeared instantly.

Seems to me the move photo code needs to update a cache for the thumb that was moved and then this would not be an issue. The issue was in the "Recent Photos" block on the index page.

Chuck S · June 24th, 2008, 08:35 AM

Yes true but where we move a photo it would appear we do update the cache so its all about checking what instance to see in the code.

what actions do you take to move a photo

Halfhidden · October 20th, 2009, 04:48 PM

Oddly enough I'm experiencing the same problem. I moved some photos from a personal album to a sub category. Now the thumbnails in recent pictures show "No Thumbnails"
I have cleared cache in browser and don't have category cache enabled in options...

Chuck S · October 20th, 2009, 04:49 PM

url?

I would think category cache but you say yours is not enabled. Plus this issue is quite old as well.

Main Index - Picture Penzance Photo Gallery

Chuck S · October 20th, 2009, 05:04 PM

Okay what happens if you put your cache time to 0?
