I'm a relatively new member with a developing shop.  I need a few pointers and suggestions.  I have very limited resources and internet experience.  First:  The banner and profile seem to require exact pixilated photos.  Is this true and is there a way around it without a camera that will pixilate.  I've tried it on my computer an it is proving extremely difficult to get it right.
Second:  Does google search by title, key words or both?
Third:  My previous experience is with physical shows,  I could use some specific suggestions for promotion.

I've found a site that I'm finding useful.  Check out 34 Ways To Promote Your Online Shop Like A Pro.  That in conjunction with browsing the bits in the forum are helpful.
