I'm experiencing technical difficulties.

My blog background is like a wool sweater that went through the dryer. I made a spring background (the same way I have been doing it since last year) that coordinates with my header but when I upload it to photobucket it is too constrained and it looks like it is way too small for the space. I don't know what to do at this point. I don't know if upgrading to pro will fix it or not but I am ticked off right now, big time. If you have any tips or helpful advice I would love to hear it. TIA!
