Hi,
I changed your HikaMarket configuration to not force the size of the vendor image.
We will fix this issue in the next release in order to not apply the "force size" if no size is specified for the width/height.
About the popup, you where using the "bootstrap" modal system but your template is not compatible with that.
So I switch to the "mootools" popup system.
If you want to use the bootstrap modals, you will have to modify your template in order to accept them ; but the mootools one are working good so I guess it shouldn't be a problem.
