I know you’re good... so can you share with me what the white-on-black insert asserts...
>>white-on-black insert asserts.
I concurr. The insert with a black background appears to be an example, pasted on, to illustrate zip file embedding/appending.
It does not appear to reflect the actual contents of pizza.jpg
I took it to claim that the pizza girls pic had a zip archive embedded in it. However, HLPhat has explained why that isn't the case above in #181.
The image is 24248 bytes long and ends with a JPEG end-of-image marker (FFD9). Nothing follows the EOI. The black-background stuff is simply an example of how a zip archive could be embedded in an apparent image attachment.
It does contain two instances of 'PK' (Phil Katz). But both are coincidences. Neither is the start of a zip file header.
