When uploading images to Salesforce Marketing Cloud, keep these guidelines in mind:

Impacts on Load Time
Image size and email weight affect your load time, and it can be risky to play with the amount of time people are willing to wait to see your messages. We know that subscribers only spend a few seconds reading email, so if they have to wait longer than they expected to even see the email, you'll lose their attention.
The easiest way to decrease load time for emails is to reduce the loaded email weight by using compressed images or fewer images.
The faster images load, the faster the email renders.
Plan for Missing/Blocked Images
If images don’t load on your recipients’ email, it may be impossible to get your message across. To prevent loss of your message, include descriptive alternative text (alt text) for your images.
