StrifeX,
I fixed my problem above all is working fine now .. It seems that when I installed the new version, it did not overwrite the plugin in hook "profile_updatesignature_start" instead it created a new one ... So I went to Plugin Manager and saw that I had two "HS - External Signature Image Size Limiter" in that hook, I hit EDIT on both of them to see which one of them was the old one from the previous version and just deleted it ... Now all is fixed and no errors appear when Saving or Previewing a Signature. Users who upgraded from your previous version might experience this problem since the new installation does not overwrite the old plugin in that hook, just creates a new one and having the two of them causes the error ...
