Hi guys,

Noticed an inconsistent bug on Gallery 1.7 and Revo 2.3.3 - In that the creation of the thumbnail fails every now and again - particularly on Safari iOS... Instead of creating the thumb, I just see a broken image...

Looking at error log. I have many error loops of the code below.

I have a temporary fix to remove the use of the [[+thumbnail]] and replace with [[+image_absolute]] - but would rather have the thumbnails generated correctly by MODx... Any ideas on a fix???

It seems to happen, after I click a thumbnail on iOS - I am using FancyApps to float the [[+image_absolute]] above the main page, then when I return to the main gallery page - the thumbnails all disapear and are shown as broken images - the error code as below then appears in the error log...

Error logo code loop:

Looking at error log, I think this error is linked to the use of Retina JS on this site - seems this person had the same issue > https://forums.modx.com/thread/86659/retina-js-and-phpthumb-add-2x - retina.js seems to be the issue I think?

I can confirm - make sure you are running v1.3.0 or later of retina.js - then add "data-no-retina" to your Gallery Thumb chunk and this should solve this bug...
