Opening it up on my iPhone gives me the new image, so it's probably a browser issue - but annoying all the same.

EDIT: yeah - clearing the log somehow helped.

EDIT_2: but only for the R21... for this Jetta, the old image still shows

I keep pressing F5, but nothing happens.

I see the same pic both times suggesting it has worked. Have you forgotten about F5 to refresh cache?

I have a problem. I would like to replace the mainpic of http://imcdb.org/vehicle.php?id=962933 with http://pics.imcdb.org/4290/r21skl86.jpg - but whenever I do, I get a message saying "picture has been sent successfully", and it's the same old picture.

Yes that's because you block ads. Solution: unblock ads on IMCDb
Problem is that it may also be blocked for other people then.
If you wish to "rename" them you can simply re-upload them under another name, the old ones will be deleted when I do the clean of unused files every few months.

Okay, bizarre idea... but might it have something to do with adblock?

EDIT: it must be, because I see the thumbs when I'm on my iPhone... False alarm, folks!

I've noticed a bug (I think) - whenever I name a thumbnail 'ad', which I used to do for some Audis, they turn out invisible:

http://imcdb.org/vehicle.php?id=325083#Comment1813126

Now, I know the images exist, as when editing the comment and copying the filename of the image takes me to the image in question:

http://pics.imcdb.org/4290/ad2.8.jpg

If the bug is not solvable, I might want to rename those concerned, as there aren't that many. I'm just interested in what might have caused this bug - as it's obviously something recent (I didn't notice when I posted the thumbs initially).

I included only those who had more than 1000 pics on the server
(many of those you upload are for replacement and so are deleted once used)

Note that it is not a competition

What about me?
