Yup. You can work around that by using @finally:

for (i = 0; i < count; i++)
{
NSAutoreleasePool* pool = [NSAutoreleasePool new];
@try{
NSImage* tempSource = [[[NSImage alloc] initWithContentsOfFile:sPath[i]] autorelease];
// autorelease tempSource to ensure that we get cleaned up if anything in 'some code' throws an exception.
// pool will automagically be released later if an exception does happen and [pool release] get bypassed.


		// some code
	    }@finally{
	        [pool drain];
	    }
	}

I also changed the pool calls to the current recommended names: +new and -drain.
