How to clear iPhoto cache

None of them if you want to use iPhoto to manage your Photos. The whole library if you don't.

If all you use iPhoto for is to transfer the images to your machine, then don't use it. Use Image Capture (in the Applications Folder) for that.

1 - you can not delete or modify anything inside the iPhto library using the finder without corrupting yoru library

2 - how are you deleting? If you delete form an event and then empty the iPhoto trash the photos is gone form iPhoto - all versions and edits, etc are gone - depending on the version of iPhoto (which you do not share) you may have to empty the system trash too

3 - As TD notes you need to make a decision - if you are going to use iPhoto then do - if you are not then don't and use Image capture or the finder - iPhoto is not a photo viewer and it is no an efficient photo downloader - Image capture is designed specifically for "capturing" and preview for viewing

You can use a card reader to copy the photos from the camera's memeory card to anywhere you'd like. They will be in a folder, possible named Canon 100, which you can just drag to the Desktop, rename the folder to whatever you want and move it to it's final destination. No need for iPhoto or any application.

OT

and if you want help you need to answer our questions

2. okay, I need more help on what you said "...you may have to empty the system trash too." More explanation please.

With the introduction of iPhoto 9 (11) when photos are deleted from an iPhoto library and it's library emptied the files are moved to the Trash bin in the Dock. This gives the user a second chance at recovering photos accidently deleted from the library.

To remove the files from the hard drive the Trash bin in the dock must be emptied as Larry pointed out.

and you still have no answered the first question

how are you deleting?If you delete from an event and then empty the iPhoto trash the photos is gone from iPhoto - all versions and edits, etc are gone - depending on the version of iPhoto

Exactly how are you deleting the photos?

IF you delete photos in iPhoto from events and empty the iPhoto trash then the photos are gone form iPhoto - depending on the version of iPhoto tha tyou hyhae (and still after multiple notes ) have not shared you may need to empty the system trash

So once again Exactly How Are You Deleting the photos?

It is impossible to assist if you continue to refuse to answer questions and tell us what you are doing
