I want to be removed “_Thumb” from the image URL _Thumb.
I know I should use STRIP on site config, but do not know how

Hi there,

If you would like to remove _Thumb from the image URL so …Omoomi_Thumb.jpg becomes …Omoomi.jpg, you can use find_string and replace_string in the site config file for this site like so:

find_string: _Thumb.jpg
replace_string: .jpg

If you would like to remove the image completely if it contains _Thumb.jpg, you can do the following:

strip: //img[contains(@src, ‘_Thumb.jpg’)]

Hope that’s some help.
