I created an interactive 'button' to create an enlarged image upon rollover of the thumbnail (just using normal, rollover states). Works well, except that the enlarged image size is what is considered rollover, and it's taking up most of the page. The image is the right size, but the rollover is just too big. Is there a fix? Or another way to accomplish (ie, the thumbnail size is all I want to rollover, not the enlarged and hidden large image)?
What hinders you to resize the button? Or what hinders you do post a screen shot to more clarify the problem for us?
The button size is the button size. Different button states may appear to be a different size but the button itself is not.
You could have one button become hidden on rollover and display another but I see very little point in doing this with rollovers. That is not what I would expect in the behavior.
