If you’re on a slow or mobile Internet connection it’s sometimes useful to know how much time the file/attachment upload will take. Take a note of what the combined size is (in MB or GB), because you might need this to see if it’s over the file attachment size limits for your email provider (and you can also use it for estimating the time to upload below).In Windows, you can do this by selecting all the files in the folder (you can press Ctrl-A while in the File Explorer window to select all files), then right-clicking on the selection, and choosing “Properties” (for Macs, see here for how to check the total size). Now, check the total size of the files you want to send. If you only want to send specific photos out of a large batch, it’s worth creating a temporary folder and copying those photos into that folder, for easier management. First, check the total size of the files you want to sendĬollect or copy all the photos you want to send into a single folder on your computer. The same suggestions can apply to any collection of images, even from iPhone/Android phones or tablets, however for a large amount of image files, we recommend transferring them to a laptop or desktop first as it makes it easier to deal with compared to using a mobile device.

For the purpose of this article, we’re going to assume that you have a collection of image files, probably from the memory card of your compact camera. This problem only becomes more difficult as camera and smartphone image file sizes continue to increase. But it’s not great at everything – if you’ve tried before to send a large number of big file attachments, you might have run into difficulties such as message rejections, failed sending and more.
