You should make sure your textures have power of two dimensions (ie. 256x256, 512x512 etc). Textures of arbitrary dimensions (NPOT) bring all kinds of mapping trouble in WebGL.

If you are unable to resize textures server-side, you can do it client-side. This link has some sample javascript code, as well as other relevant information: http://www.khronos.org/webgl/wiki/WebGL_and_OpenGL_Differences
