is there any way to force Gallery3 to rebuild all thumbs and resizes?

I've made some changes to my photos and I want to generate new thumbs and resizes.

I've tried with "Maintenance" -> "Maintenance", but I'm getting
"Rebuild Images... Updated: 0 images. Total: 0."
as Gallery3 states "All your photos are up to date".

I've tried to remove all old thumbs and resizes from "/var", but that left me without any images except fullsizes. Gallery3 would not generate new ones.

I've tried both ImageMagick and GD.

is there any way to force Gallery3 to rebuild all thumbs and resizes, or to make new if there (in "/var") are none?

yes. cropped some of them.

in gallery2 I would just run "Build all thumbnails/resizes" from "Maintenance" page, and everything would be ok.

any way to do something similar in gallery3 ?

What I do, as a workaround, is changing the resize & thumb sizes from: Admin -> Appearance -> Theme options and save, then returned them as they were and save again. After that, you can go to the maintenance page and rebuild them.

If you are comfortable manipulating the database tables directly (IE: using phpMyAdmin),
there is are fields in the items table that holds a boolean value of true (1) or false (0). The field name contains the word "dirty". By setting them to true (1), when you use the maintenance option to rebuild the entries it will perform the service for all the entries flagged.

Thank you, griffinmt, for your notes on rebuilding images. I recently needed to update all my resized images, and found your post very helpful.

I used a MySQL query something like the following to mark the records for all the photos in my database at once.

UPDATE items
SET resize_dirty = 1, thumb_dirty = 1
WHERE type = "photo"

I thought I'd post the query here in case someone else found it useful.
