Question: On my portfolio site at <http://samnorris.co.nz> I have an animated .gif image - the astronaut with the heading underneath: "Protecting the galaxy one pixel at a time"...

I'm not sure if it's just me and my monitor or not, and it is only very, very subtle but I can notice the background texture is not blending very well to the background texture on the page (which uses the same texture) and at some resolutions, and especially while scrolling I can see a visible square-like 'halo' around the image, as if the texture on the gif is slightly lighter than on the page or something.

I have tried various Photoshop export settings including Perceptual, Adaptive and Selective and quality: bilinear, bicubic ect. but nothing I have tried so far seems to solve it.

Incidentally, I was using a different background texture before which didn't seem to suffer from the problem, so maybe the problem just lies with the (complexity of?) the texture itself? or is there some way I can make sure the background texture in the .gif blends perfectly to the pages' background?

Here is the actual image itself:

and the background texture used on the page, if it helps at all:

It only seems to be a problem with the GIF and none of the other JPEG's or PNG's on the same page/section which use the same background texture either.

Answer: 
I had this same problem and did not find any other discussions addressing this issue, so I thought I'd post the solution for anyone else looking for it here. I fixed it by changing my document resolution (under Image --> Image Size). I started with a 1024x1024 document size, thinking it needed to be the same as my texture resolution. I updated it to 4096x4096 and found my object rendering much improved. The texture sizes are independent of your document size (I am new at this, so that probably should have been obvious to me to begin with).
It may also be that you are zooming the image. If you want the object to be bigger, just bring it closer using the tools that are specifically for 3D, which are placed over the working canvas.
This happened to me. I could see the 3D model super pixellated, and it turned out I was zooming it.
