This is a copy of a message I posted in the Essential theme forum and a copy of the reply I received from Julian.
We have just installed Moodle 2.6 (Build: 20131224) and the Essential theme version 2.6.2 (Build: 20131202) on our test site and we are having a problem with the display of images in ie8, ie9 and ie10.
All images are displaying at their actual size rather than the size that is specified in the Appearance tab. For example, if the image is actually 200px x 200px, but has been set to display as 100px x 100px in the Appearance tab, the image will be displayed at the following sizes in the various browsers we have tested:
In ie8, ie9 and ie10 - 200px x 200px
In Firefox - 100px x 100px
In Chrome - 100px x 100px
In Safari - 100px x 100px
In ei11 - 100px x 100px
As our organisation cannot upgrade to ie11 due to other system incompatibilities, and the fact that many of our students will still be using these older versions of ie, is there any way for this to be fixed so that the images display at the correct size in these ie versions?
This is not an Essential bug but one with Bootstrap in general. You will find the same thing Happening in the Clean theme.
As such I do not have a fix to offer.
Does anyone have any suggestions how we can resolve this problem as we have many courses that are affected and manually resizing images will take many hours.
