Just out of curiosity, when you hit 'ctrl +' or 'ctrl -' does it indicate that your screen resolution is more than 100% or less than and not right on 100%? That's the only way I can duplicate what you describe. WIX operates as a website engine (I don't code - I merely use their tool to design). The images overlay the text and I either add space or subtract it to make specific room for them. I try not to save and publish between edits until I correct all apparent errors but occasionally I miss a few. I've gone over the last adjustment with a fine toothed comb and all appears proper at 100% screen resolution. I use Chrome, as well, and I must remember to refresh the page between views if I've made any adjustments.
