what ai is ideal for travel style posters from everyone’s experience? ideally free, if not a low cost one? struggling to find anything decent that actually generates images at a scalable size without cropping loads of image

i’m new to this and am really struggling. when generating an ai image i then upscale it but when resizing to different aspect ratios it ends up cutting some of the image of everytime. i don’t know what to do to get round this. Is there a way to generate the image so it will be able to be resized to each aspect ratio without cutting any of the image off

does anyone know any good ai platforms they use to generate images for posters that are either free or offer a free trial. I preferably want to test the AI first before getting into a paid monthly subscription.

i’m using ai to generate my poster images but for some reason no matter what they always come out long and thin even when i prompt for a certain aspect ratio. as a result whenever i try to resize it into any other aspect ratios it never fits properly (as in some of the top and bottom get cut off). how do i fix this?

Just starting out and need some help. can anyone recommend what sizes i should offer to start with. I’m thinking i’ll just offer A sizes and most 2:3 3:4 4:5 sizes. just wondering which exact ones to do. For example 16x20. Also am i correct in thinking that as long as i have a A1 size and the largest 2:3 3:4 and 4:5 size saved on my computer. When i make a sale printshrimp deals with the exact size the customer has ordered? or do i have to manually resize the image?
