Thumbnail images do not appear after update to 4.7.

Could you provide more details? Thumbnails still work after I upgraded to 4.7. Make sure you have the latest version of everything (most importantly image.module and img_assist).

I can only second this. I've tried everything. Different themes, different input types, different browsers etc. The filter just does not work and the html code is missing the img tag. It does work with older version together with 4.6.x

Some have reported this sort of behavior if there is a malformed value for "Max inline image size allowed" in the settings page for img_assist - and that the malformed value appears during the update to 4.7. See: http://drupal.org/node/64259

I also cannot get img_assist images to show up in 4.7.

I just upgraded four Drupal 4.6 sites, all of which used the image module (but not img_assist). On one of the sites (and only one), some of the thumbnails were no longer there (in the database or in the filesystem). I tracked it down to a missing variable 'image_updated' which is used in image_display(). I manually created this variable, with today's date, and everything worked (the thumbnails were re-created from the originals). Check the variables table and make sure it has 'image_updated'.

This may not have anything to do with the problem(s) discussed here, but hopefully someone will be able to figure out this issue. I'd figure it out if I could reproduce it, but I've installed img_assist dozens of times on Drupal 4.7 and I've never seen this problem.

I had the same problem until I ran into a tip from Chad McCully (http://drupal.org/node/66782):

Go to "admin->input formats" and you should see a list of the standard three input formats. For Filtered HTML, select configure and check the box next to "inline images."

I had this problem until I realized that I was experiencing the problem on one of the new content types I'd created with CCK. When I edited my new field, in this case a body text field, I enabled filtered content. Previously it was just plain text. The image then displayed correctly.

hi Folks,

that access priv problem might be the reason why it doesnt display ANYTHING

but check my problem in http://drupal.org/node/79470

I suspect that the different tag syntax used is the plain reason

I had it display the FULL-SIZE images where thumbs belonged and vice versa

e.g. what was

[img_assist|fid=17| ...

must now be
[img_assist|nid=1010| ...

and the new type of linking is specified by yet unknown tags..

|link=none|align=left|width=160|height=113]

It's still unclear how benjamin planned to migrate all those tag in existing Drupal 4.6 installations...

if you used them (instead of the HTML code) then you REALLY have a problem now
