Spam Gmail Isn’t Stopping

So.. over the past few weeks I’ve noticed a complete increase in spam that is defeating googles spam filters. The premise is simple.. take an image and embed your spam into that image.. the spam filiters can only read the file name.. the file names usually look fairly common. Here is an example:

I’ve been pondering this issue this morning.. and google is going to be HARD pressed to be able to filter this spam if the spambots use a large enough sample of servers.. about the only possible way for google to eventually stop this type of spam is to develop the ability to quickly read text on an image.. and even then just think of all the garbled insanity that is sent on a daily basis through images.. it seems to me that could really lead a large number of legit emails being filtered.
