CUSTOM FIELDS / ADVANCE SEARCH BAR / FILE UPLOAD

Hello,

#1
2. Can I change the round icon for each CPT and set the position in search bar (the multiselection options icon appears always in the last position)?
(see geo6screen)

#2
I set this «upload file» field and I wrote the additional css
.geodir_thumbnail {background-size: content;}
.geodir-custom-post-gallery {width: 100% !important; border: none;}
but the image does’t keep the proportion – it is cut (the original size is 400 x 575px).

I want the full width of the column keeping the proportion without «cut»
So – for different image size proportionI I will have same width and several proportional heights.
For example, if maximum column width is 150px for a img of
350×350 >>> I’ll have 150×150
600×300 >>> I’ll have 150×75
300×600 >>> I’ll have 150×300

Thanks!
