So Many Thumbnails

Hi @decard

If you want to clear thumbnails generated by FooGallery, you can simply do so by clicking on the “Clear Thumbnail Cache” button shown in this linked image: https://prnt.sc/-NubRp7Ao_Ju

Thanks.

Kind regards,
Elvis.

@elviiso

hi @decard,

Shortpixel will optimise thumbs for both thumbnails auto-generated by WP, and also thumbs generated by FooGallery.

We have no control over the thumbs WP creates when you upload a new image to the media library, but in FooGallery, we control certain thumbs based on the settings you have chosen for your gallery.

The “Thumbnail Size” setting will be the main one, but also the Retina settings you have chosen for the gallery.

Example : if you have a thumbnail size of 100 x 100, then FooGallery will create a thumbnail which is 100×100 to be shown in the gallery. If you have retina 2x and 3x selected, then there will also be a 200×200 and 300×300 thumbnail generated to cater for retina displays.

Also, if you changed your thumbnail size many times when setting up your gallery, then that would also cause more thumbs to be generated at the different retina levels. If that is the case, then it is a good idea to clear thumbnails, as Elvis suggested. Which will clear out any unused thumbs. That button is found on the gallery edit page.

I suggest you do not choose all the retina options, which will reduce the number of thumbs.

@elviiso – let’s create some more detailed docs around this, as I am sure this will be useful info for others with a similar problem

thank you. (i see i have to refresh to see latest – and i am not getting any notifications which i will have to check)

thanks for info but as it happens i have not changed or added any retina options; but i attempt to check just what is happening

however you have STILL not told me how to clear cache – because that option mentioned above DOES NOT EXIST

(and i would be cranky if you are sending me options that only exist on a stupid mb app!)

kind regards

PS yes. this was one of the hundreds of sites that i still have to update my email address from old defunct one

please note that in fact there were NO retina settings – at all!!

so that is NOT the reason

wtf does this seem to marked as “Resolved”?

hey @decard,

In my reply, I said “That button is found on the gallery edit page.”

Edit the gallery, and on the bottom right hand side, you will see a metabox with the button, as Elvis showed in his screenshot.

I have tested this on a brand new WP install with FooGallery installed and the metabox (and button) are both there. If the Thumbnails metabox is not showing for you then check “Screen Options” which is at the very top right of the gallery edit page, and make sure “Thumbnails” is ticked.

But besides the thumbs created by FooGallery, if you have many sizes registered in your WP install (by your theme and other plugins), then all those thumb sizes will be created for each image uploaded and Shortpixel will pick up all of them. That is outside of the control of FooGallery

hi there

1. you seemed to have missed the bit where i said that NO retina thumbs were selected

2. Screen Options has everything ticked as default

3. i see a Thumbnail option on bottom RHS (WHEN i go to edit Gallery – not n global options), and the ONLY option it has is ‘Force Original Thumbs’

4. i do not know where any other Thumbs would be created that Shortpixel finds and tells me there is a 1,000 Thumbs.

regards
