This is so beneficial as it contains the essential core elements needed for collaboration between design, operations, and development teams in real work situations!! It would be amazing if you could create more core lectures like this that are needed for practical work!! This is a lecture that gives great strength to solo designers!! Highly recommend!!

I've had so many headaches with image issues in projects. I used to think image processing problems like processing and displaying images were simply development issues. After watching the lecture, the concepts are now crystal clear. Through the lecture, I clearly understood how to communicate with team members and how to design in projects. In particular, having example images for understanding with each explanation was fantastic. The video quality was so good that I could get a sense of what situation you were going to explain just by looking at the pictures. Thank you for the great lecture.

What you will gain after the course

  • I can understand the causes and consequences of image issues.

  • You can understand the image upload flow and respond in advance.

  • You can set the aspect ratio, resolution, and format to suit the service.

  • You can understand the structure of automatic resizing processing in the server/CDN.

  • You can set separate image resolution standards for each purpose.

Image issues can be prevented from the start.

In many products, image issues always surface too late.

Aspect ratios are off, resolutions are pixelated, loading is slow, and costs increase.

The cause is mostly due to a lack of an image policy.

This course provides strategies to prevent these issues in advance.

Regarding user image upload settings, separating resolutions by purpose, and ratio/format settings, etc.

Let's take it step by step from now on.

Are you having these concerns?

I recommend this lecture!


The agonized designer

'What should the image area be set to?'


Exhausted developer

'No more repetitive QA...!'


Anxious planners

'If this happens, the schedule will be delayed again…'

After taking this course, you will be able to

✅ You can predict and prevent image issues that occur in practice in advance.

✅ Image standards between planning, design, and development become clear, reducing collaboration conflicts.

✅ By being able to control the quality of user-uploaded images, service stability and user experience are improved.

✅ You can optimize service performance and costs by reducing operational issues such as wasted traffic and loading delays.

✅ By designing images to appear without distortion across various devices, multi-platform responsiveness is strengthened.

    Image processing is quite a headache in development environments as well. Processing and handling images with code on the server or app side is quite troublesome. When image size issues are added on top of that, handling just that alone could take several days or more in the worst case. This lecture is not a technical lecture covering code-based processing, but it will help reduce the trial and error that can occur during development. This lecture does not cover technical content about image processing. It's more like a methodology for planning image sizes. This means the target audience is web designers or planners rather than developers. It's not a difficult or heavy lecture. It's fine to listen to it lightly during commuting hours. It's worth saving a cup or two of coffee. If it can reduce the cost of fighting between planning and development perspectives, it might even be considered more profitable.
