The first painting to catch my eye was this one of what is apparently a young suicide bomber wearing a mask made out of a kaffiyeh. The Arabic words behind him say, over and over, "I will not accept a little" or "I will not accept a pittance," apparently referring to the desire for a Palestinian state that occupies all of modern-day Israel, and not just the West Bank and Gaza. In other words, it is a call for the elimination of Israel, seemingly with suicide bombing as the means for achieving this. (Thanks to evariste for the translation.)
Here's a close-up of the central figure, with the bomb attached to his waist more clearly visible (which is reminiscent of this photograph of a young Palestinian being groomed to become a suicide bomber).
Next up was this photograph of two mannequin-hands holding a "blood"-soaked globe. You might wonder: what does this have to do with Palestine or Israel? The answer: everything. Because the image of greedy hands grasping a (frequently bloody) globe is one of the most notorious anti-Semitic illustrative themes of the last century. This motif was (and is) often used as an illustration for covers of the anti-Semitic tract The Protocols of the Learned Elders of Zion.

Here is a classic example from a 1930s-era French-language edition (provided here as a comparison -- it was not part of the exhibit). In most reditions, the hands grasping the bloody globe belong to a greedy Jew who wants to take over the world. I suppose this is the message -- which is widely believed among Palestinian militants -- that the artist who took the photograph wanted to communicate. (Notice also how the position of the continents is identical in both images. Coincidence?)
