Hello

I like what you have done. Thank you.

1. navigation buttons will not work with images that have a capital suffix

fileio.go LINE 77
if strings.HasSuffix(v, ".png") || strings.HasSuffix(v, ".jpg") || strings.HasSuffix(v, ".jpeg") ||

**** I have it working by checking lowercase suffix as below

if strings.HasSuffix(strings.ToLower(v), ".png") || strings.HasSuffix(strings.ToLower(v), ".jpg") || strings.HasSuffix(strings.ToLower(v), ".jpeg") || strings.HasSuffix(strings.ToLower(v), ".gif") {

2. image orientation is not correct when viewing portrait images taken with my DSLR

**** I have it working by adding an import and changing one line of code

fileio.go
import "github.com/disintegration/imageorient"
and changed line 67 to
a.img.OriginalImage, _, err = imageorient.Decode(file)

I tried to open picture with 10Mb size around 4K resolution and it took 1GB in RAM which is Huge.

it doesn't seem an "image-viewer" ~

Hi,

It would be great to be able to see thumbnails of the directory. Infinite scroll or paging.

In my use case I could have 2000+ cannon DSLR images in a folder. 3mb + each.

I tried a very crude implementation but it was way to slow. Almost workable if I paged the thumbnails to say show 12 at a time. Thumbnails created on the fly. I did find a fyne implementation of showing thumbnails of large images on the fly that used MD5 and caching..... lightning fast.

Hello

if the image has not been edited the program crashes when trying to save

*** my fix was to check a.img.EditedImage is set
*** I also added case ".jpg" for encoding

fileio.go

// if file has not been edited
if (a.img.EditedImage == nil ){
   a.apply()
}
switch writer.URI().Extension() {
case ".jpg":
	jpeg.Encode(writer, a.img.EditedImage, nil)		
case ".jpeg":
	jpeg.Encode(writer, a.img.EditedImage, nil)
case ".png":

hello

is this project going forward? May I ask in what direction?

Could you add cropping / annotations ?

Thanks

from go.sum file , i see github.com/nfnt/resize is imported , but image resize feature is not present on user interface , or i just missed it ?

It would be great to have a zoom feature with either a slider or a plus and a minus button.
