We use Next/Previous buttons as controls in our image gallery. I'm in the process of implementing responsive design, so there is a limited amount of space that I can be used for these buttons. I'm wondering if using "Prev" instead of spelling it out as "Previous" will confuse users or if they will generally understand it. The buttons will also have arrows pointing in the respective orientation.
To clarify, the buttons are oriented vertically (along with the text) so that they match up with the height of the image. So the real issue is the height of the previous button when we get down to mobile size.
