问题 So generally, i don't have a problem (yet), but I need advice. I want't to make a page where a user can upload his/hers image. But the upload should not refresh the page as the other data that a user enters will get lost. I know there is a bunch of ajax and php uploader posts, but here's the thing.

由 别来无恙 提交于 2019-12-10 01:11:51
问题 I want to disable the "Take Photo" option in an iOS app (WKWebView based) and force users to select photos from library or iCloud. I can force users to use the camera by the capture boolean attribute: <input type="file" accept="image/*" multiple capture> But, I can't found anything similar to do exactly the opposite (disable camera). Is that possible with any other HMTL attribute or a different value for capture ? Similar question was asked here: How to disable take photo on file input iOS 6,

问题 I want to create an application server that serves html content which contains links to static images served by another server on a different domain. The images are uploaded by users through the application server.

Currently, I adopt Carrierwave for users to images. However, I hardly find a solution for image security, i.e. how to set image authorisation for the uploaded images to only let certain user in the same group to view?
