Thx. I tried verypdf but unfortunately it just closes its command prompt window without doing anything. PDF is , as others said, the worst ebook format to convert from. I can confirm this after the attempt to convert pdf to epub using Calibre (source document was column separated magazine document and it was all mixed up as one)

If you cannot actually delete the images (because: see above), perhaps an acceptable alternative would be to use available utilities to reduce the quality of the images, and change them to grayscale.
That would drastically reduce the file size of your PDFs, which is often the motivation to remove the images. It is possible that changing the image attributes might disrupt the "flow" of the PDF document that you prize. Only trial-and-error testing of different combinations of criteria will tell you if that is so.

Thx. you clearly got my point of asking
yes it was the file size that I am concerned with, especially for the pdf that contains one hel of a lot of images that I don't need to view. I am usually text-oriented person
It is a nice idea to utterly reduce the quality to the last drop, instead of simply removing them. But Isn't pdf basically unreflowable anyway? If the image in the page is gone, the image is just replaced by empty space and does not affect the page layouts, imho

Thx. I will try them out. k2pdfopt seems to serve different purpose (reflow pdf text to fit in smaller screen size by cropping the original pages in half or more) but there're options that fiddle with output image quality.
